DRAM frequency switches are executed in firmware and can change the configuration of the DRAM PLL outside linux. Mark these CLKs with CLK_GET_RATE_NOCACHE so we always read back the PLL config registers and recalculate rates. In current DRAM frequency tables on 8mm/8mn only the maximum frequency uses the PLL so it's always configured in the same way. However reading back the PLL configuration is the correct behavior and allows additional setpoints in the future.
